More on long-term access to data

The presentations from the DCC conference on Ensuring Long-term Preservation and Adding Value to Scientific and Technical data (Edinburgh, November 21-23, 2005), are now online. See especially the three following:
  • Jens Klump and eight co-authors, Data centres and their role in publication and access to data. Abstract: "In 2003 the ‘Berlin Declaration’ was published as a guideline to policy makers to promote the Internet as a functional instrument for a global scientific knowledge base. Since knowledge is derived from data, the principles of the ‘Berlin Declaration’ should similarly apply to data. However, access to scientific data is hampered, in part, by structural deficits in the publication process. Thus, applying the ‘Berlin Declaration’ to data requires a publication system for data that goes beyond what is in place for ‘traditional’ media. The criteria of accessibility, persistent identification and long-term availability need to be met in order to comply with the declaration. The project ‘Publication and citation of scientific primary data’ has shown prototypically how these criteria can be met and soon a publication system for scientific data will be available to the scientific community. In the structure set up within the project, data centres act as registration agents encompassing all functions necessary for the publication of scientific data, pointing towards a new role for data centres in addition to their current archiving mandate."
  • Jeroen Bekaert and Herbert Van de Sompel, Access Interfaces for Open Archival Information Systems based on the OAI-PMH and the OpenURL Framework for Context-Sensitive Services. Abstract: "In recent years, a variety of digital repository and archival systems have been developed and adopted. All of these systems aim at hosting a variety of compound digital assets and at providing tools for storing, managing and accessing those assets. This paper will focus on the definition of common and standardized access interfaces that could be deployed across such diverse digital respository and archival systems. The proposed interfaces are based on the two formal specifications that have recently emerged from the Digital Library community: The Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) and the NISO OpenURL Framework for Context-Sensitive Services (OpenURL Standard). As will be described, the former allows for the retrieval of batches of XML-based representations of digital assets, while the latter facilitates the retrieval of disseminations of a specific digital asset or of one or more of its constituents. The core properties of the proposed interfaces are explained in terms of the Reference Model for an Open Archival Information System (OAIS)."
  • Jessie Hey, Steve Hitchcock, Leslie Carr, and Tim Brody, Preservation for Institutional Repositories: practical and invisible. Abstract: "With good prospects for growth in IR contents, in the UK due to the proposed RCUK policy on mandating deposit of papers on funded work, and internationally due to the Berlin 3 recommendation, it is timely to investigate preservation solutions for IRs. The paper takes a broad view of preservation issues for IRs - based on practice, experience and visions for the future - from the perspective of Preserv, a JISC-funded project. It considers preservation in the context of IRs. Based on the OAIS preservation model, an architecture is proposed to support distributed preservation services for IRs. Work performed so far involves adapting the IR user deposit interface in a pilot version of EPrints software for building IRs, and determining accurate file format information using PRONOM software. The paper looks ahead briefly at the role of preservation service providers, working for the IR, within this architecture. The strategy is to take practical steps that are, as far as possible, invisible to all but those concerned with the preservation process for IRs."
